Sigma MC-11 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to Sony E)

Sigma Mount Converter MC-11 (Canon EF Lens to Sony E Body)
Electronic Smart Lens Adapter – Full AF/AE Compatibility, In-Camera Stabilization Support, Flocked Interior & EXIF Data Communication (Like New Condition)

The Sigma MC-11 Mount Converter allows full electronic adaptation of Canon EF-mount lenses to Sony E-mount mirrorless camera bodies (including full-frame a7/a9 series and APS-C a6000 series). Engineered to retain complete lens and body integration, the MC-11 maintains high-speed phase-detection and contrast-detection autofocus, auto-exposure controls, and full EXIF metadata communication.

It supports Sony in-camera 5-axis image stabilization (IBIS) as well as lens-based optical stabilization (OS) systems. An integrated LED status indicator on the side of the adapter provides visual verification of compatibility between connected lenses and updated camera firmware. To preserve image contrast and prevent stray internal reflections, the inner barrel of the adapter features a light-absorbing flocked black interior.
